Objective:To study the relationship between telomerase activity and the expression of proliferating cell nuclear antigen(PCNA) in oral squamous cell carcinoma (OSCC). Methods:Telomerase activity and expression of PCNA in 68 cases of OSCC,34 cases of epithelium immediately adjacent to carcinomas and 12 cases of normal oral mucosa were detected by TRAP-PCR-ELISA and immunohistochemical SP method. Results:The positive rate of telomerase in OSCC, the epithelium immediately adjacent to carcinomas and the normal oral mucosa was 67.65%(46/68), 8.82%(3/34) and 0(0/12) respectively. Telomerase activity in OSCC was related to the grade of the clinicopathology(P

The Eph protein family,consisting of Eph receptors and their corresponding membrane-anchored protein ligands-Ephrin,is no doubt the largest receptor protein tyrosine kinases family till now.Interactions between Eph receptors and Ephrin ligands based on their special structure might make the Eph protein family one of new targets of disease′s treatment and consequently studies related to Eph proteins and their receptors have draw more and more attention.This overview will focus on recent progresses in the classification,gene expression,protein structure,function and protein-receptor interactions of the Eph protein family and their receptors.Much of the focus of this overview is on their physiological and pathophysiological role in nervous system and their therapeutic perspective from several aspects.

Objective: To measure the fracture strength of the posterior galvano-ceramic bridges made by Ni-Cr pontic fired bonding galvano caps with highly temperature-resistant adhesive and to provide re-ference data for clinical application. Methods: A standard low dental cast was achieved with 46 missing. Five posterior galvano-ceramic bridges made by Ni-Cr pontic fired bonding galvano caps, with abutments being 47 and 45 . The low dental cast was fixed on the panel of the universal testing machine, vertical load given on the central of the pontic as the velocity of 2 mm/min. Results: The fracture strength of the posterior galvano-ceramic bridges made by Ni-Cr pontic fired bonding galvano caps was (877.00?126.53) N, the fracture strength of the metal frame was (1 448.94?51.02) N. Conclusion: Posterior galvano-ceramic bridges made by Ni-Cr pontic fired bonding galvano caps could endure the normal human occlusal force.

Objective To discuss training of the nurses in outpatient blood collection room with the digital training modular of blood sample collection to improve the quality of blood sample collection. Methods Nurses were trained with the digital training modular by multimedia,group discussion to impmve the quality of blood sample collection continuously. Results The unqualified blood sample rate in the same season after training were statistically different compared with that before training. Conclu-sions Training the nurses in outpatient blood collection room with the digital traimg modular of blood sample collection have actual direction value to improve the quality of blood sample collection.

Objective To analyze the correlation between the tubular gastric width and the anti gastroesophageal reflux after esophageal cancer operation,and to provide reference for the choice of surgical methods in treatment of esophageal cancer.Methods Selected 60 patients who received radical surgery for esophageal carcinoma combined with gastric tube reconstruction surgery in our hospital from January 2015 to October 2015,and divided them into two groups according to the way of stomach tube anastomosis (cervical anastomosis,thoracic anastomosis) and different width of gastric tube (greater than or equal to or less than 3 cm).Namely:cervical anastomosis + greater than or equal to 3 cm group(14 cases),cervical anastomosis + less than 3 cm group(15 cases),thoracic anastomosis + greater than or equal to 3 cm group(15 cases) and thoracic anastomosis + less than 3 cm group(16 cases).All patients recieved esophageal pH monitoring for 3 days continuously from the 11 th day after operation.The monitoring indicators include:number of reflux,accumulation time of pH ＜ 4,whether there were clinical symptoms (heartburn,chest pain,pharyngeal foreign body sensation,cough,asthma,etc.) after surgery,and the frequency and time of these clinical symptoms appeared.All the patients were given endoscopic examination at the 14th days postoperatively.Observed the esophageal mucosa of patients and conducted histopathological grading of gastric mucosal inflammation.And then made a correlation analysis of gastric tube width and esophageal mucosal inflammation grade among all the patients with reflux symptoms.Results The cumulative time and number of reflux,incidence rate of clinical symptoms,and pH values less than 4 were significantly different(P ＜ 0.05).The cumulative time and number of reflux,incidence rate of clinical symptoms,and pH values less than 4 in the cervical anastomosis + less than 3 cm group were significantly lower than that in the other 3 groups(P ＜ 0.05),with statistical significance between different groups of endoscopic esophageal mucosa inflammation grade difference (P ＜ 0.05).Esophageal mucosal inflammation grading in patients of the cervical anastomosis + less than 3 cm group was the lightest.It showed a linear correlation between the gastric tube width and esophageal mucosal inflammation grading in patients with reflux symptoms.Conclusion Postoperative gastroesophageal reflux is closely related to stomach esophagus width after resection of esophageal carcinoma with tubular stomach reconstruction of stomach esophagus,because it is unable to control gastric tube width to the appropriate range.And it should be strengthened in patients with reflux related indicators for monitoring,so as to take measures to prevent gastroesophageal reflux as soon as possible to improve the prognosis of patients with quality.

Serum p-amyloid peptide(Aβ)40 and Ap42 levels in patients with type 2 diabetes mellitus (T2DM)and atherosclerosis(AS)were detected by ELISA.The results showed that serum Ap40 level in T2DM group was significantly higher than that in the control group[(274.70±159.51 vs 162.63±87.58)pg/ml,P<0.05],especially in the diabetic patients accompanied with AS[(616.95±195.13)pg/m],P<0.01].Serum Ap40 level in simple AS group was also higher than that in control group[(318.52± 188.65)pg/ml,P<0.05].These results suggest that Ap40 is a risk factor of T2DM complicated with AS.However,there was no difference in serum Ap42 levels among various groups.

Objective To design and apply the digital training modular for nurses in blood sample collection in order to improve the quality of blood sample collection.Methods Based on the principle of evidence-based nursing,the records of unqualified blood samples in the clinical laboratory department were analyzed.Then,the modular of examination item list,tube choosing,volume of blood sample,patient preparation and theoretical foundation,influential factors of the quality of blood collection,and quality information were designed and applied to train nurses.Results After training,the unqualified rate of blood samples was significantly decreased from 0.56% to 0.34% (P<0.01).Conclusion The application of digital training modular of blood sample collection can improve the quality of blood collection.

Objective To study the relationship between the change of T lymphocyte subsets and NK cells in esophageal cancer patients and radiotherapy effect.Methods The levels of T lymphocyte subsets and NK cells were detected by flow cytometry in 56 cases with histologically confirmed esophageal cancer treated with radiotherapy and contrasted to the healthy people.Results In patients with esophageal cancer,peripheral blood T cells,Th cells,Th / Ts were decreased significantly compared with the control group [(58.3±5.2) ％ vs (65.8±7.2) ％,(28.7±5.0) ％ vs (38.1±7.7) ％,(1.0±0.3) vs (1.6+2.7),all P ＜ 0.05],while the Ts cells were significantly increased [(28.8±5.3) ％ vs (25.4±5.7) ％,P ＜ 0.05].There was no significant difference between peripheral blood T lymphocyte subsets,Th/Ts ratio change and patient age,sex,tumor staging,histological differentiation and pathological lesions.After radiotherapy,the levels of peripheral blood T cells,Th cells,Th/Ts cell ratio and NK cells in esophageal cancer patients were increased [(66.9±4.5) ％ vs (59.4±4.9) ％,(40.6±5.6) ％ vs (29.1±4.2) ％,(1.6+0.5) ％ vs (1.0±0.4) ％,(16.2±3.9) ％ vs (14.6±3.2) ％,all P ＜ 0.05],while the Ts cells decreased [ (25.4±3.6) ％ vs (28.4±5.7) ％,P ＜ 0.05].The increasing degree of peripheral blood T cells,Th cells were closely related to the lesion progress,the difference was significant (both P ＜ 0.05).Conclusion Cellular immune function in patients with esophageal cancer is low.Detection of T lymphocyte subsets,NK cells can be used for immune monitoring of patients with esophageal cancer.
